Angry Gas smell in oil

My 1999 Monte Carlo has a very noisy engine. It sounds like one of the lifters won't prime. When checking the oil, I noticed that it looks very thin and has a gasoline smell. It also is over the full mark now. What might be causing the gas to mix with the oil?

Two possible conditions come to mind.

- The fuel pressure regulator has a leak and is drawing fuel via the vacuum line.
- You may have a leaky injector - one or more won't close properly, causing a massive leak that goes past the rings and ends up in the oil pan.

Get that oil changed pronto, before the bearings get ruined.

test for gas

Pull the dip stick and see if a match applied to the oil on the dip stick catches it on fire.
